The only non-invasive, and thus, safest, way to get a sample from the baby before birth is from a blood sample of the mother. The baby's DNA is present in varying amounts beginning as early as the 8th week of pregnancy. Google The American Pregnancy Association for more info. ...Read more

How do I get a paternity blood test? Do I go through my family doctor?My girlfriend is getting a prenatal DNA test. Can I do it without telling her?

Not sure who you are: I am not sure who you are at 55YO and a female. But, I doubt that you can request a paternity test in the scenario you describe. The mother of the child can request this, but the other issue is who pays for the test. The OB will know exactly how to do this but the mother of the fetus must be involved. ...Read more

And there is also mishandling a specimen. ...Read more

Is there a noninvasive prenatal paternity testing company that is credible?

Unlikely : The key words of your question are credible and non-invasive.There are reports of maternal blood being used for screening, yet this technology is far from being accepted in court. Samples of the fetal membranes (cvs) or amniocentesis are accepted methods, but both pose some risk to mother and baby. Most paternity issues are handled by off site labs, hospitals or patients can obtain the test kits. ...Read more

Got two men tested for paternity test on my bby. I only slept with those two about two or three weeks apart. Both test came back negative how is that?

Impossible...: If you only had sex with two men, then one of them is the father. Either there was a "testing error" (labs are reliable, if they got the correct specimen this is very unlikely), one of the two men didn't actually get tested, or you have forgotten about another possible father. Good luck. ...Read more

What are some recommended locations or labs to do non-invasive paternity testing in texas (dfw) area. What are your thoughts on the tests accuracy?

The most accurate: Test is a blood test. Physician-ordered comparative genomic hybridization, costs ~ $2, 000/person. Each putative father usually pays for his own & shares the cost of the newborn's test. Saliva testing by proprietary labs (e.g., 1-800-whosyourdaddy) are often inaccurate. If either putative father has a family history of an inheritable genetic disorder, his insurance may cover part of the cost. ...Read more
